We propose a way to increase the wear and crack resistance of the main working tools for roller mills. Bimetallic rollers (with a diameter of 252 mm and a length of 1620 mm) are produced by sequential pouring of alloys with similar temperatures of phase transformations. The microstructure, phase composition, redistribution of alloying elements, and the properties of bimetallic materials are studied. The results are used as a basis for the development of a technological process for the production of bimetallic milling rollers by the method of centrifugal casting. The implementation of this method makes it possible to improve the reliability and durability of rollers in the course of their operation.

双金属离心铸造轧辊的结构与性能

我们提出了一种提高辊磨机主要工作工具的耐磨性和抗裂性的方法。双金属辊（直径为 252 毫米，长度为 1620 毫米）是通过连续浇注相变温度相近的合金制成的。研究了双金属材料的微观结构、相组成、合金元素的再分布和性能。研究结果可作为开发采用离心铸造法生产双金属轧辊的工艺流程的基础。这种方法的实施可以提高辊在其运行过程中的可靠性和耐用性。
